You can find information of any kind on the Internet. A schoolboy from Hong Kong used that opportunity. The Hong Kong police arrested a 15-year-old boy the other day, who brought a self-made bomb to school. He read the instructions how to make the bomb on the net. As a result of the unknown circumstances, the bottle of gun powder and metal balls exploded right in the boy’s backpack. Fortunately, no one suffered. The police were so worried about that incident that they sent 50 of their attendants to that school, including the one to neutralize the bomb. The probe has been started towards the young terrorist, although the head master said the boy just wanted to surprise his pals.
